Police searching for a 70-year-old suspected gunman, who allegedly killed one person in a Phoenix office complex Wednesday and wounded two others, found the suspect’s car with a body inside, Fox affiliate KSAZ reported. The body has not yet been identified.

Arthur Douglas Harmon allegedly opened fire at the end of a mediation session Wednesday morning at a three-story office complex in north-central Phoenix, police said.

One man — identified by police as 48-year-old Steve Singer — died hours after the shooting. They said a 43-year-old man was listed in critical condition and a 32-year-old woman suffered non-life threatening injuries.

“We believe the two men were the targets. It was not a random shooting,” said Sgt. Tommy Thompson, a Phoenix police spokesman.

Thompson said the gunman arrived at the office building about 10:30 a.m. and got into a dispute with someone, a conflict that escalated to the point where the suspect drew a gun and shot three people.
